METALLIC SPECIFICATION forming part of Letters Application filedFebruary 11. 1389.

To all whom it may concern.-

Be it known that I, MILLARD F. IIAMSLEY, of Nashville, in the county ofDavidson and State of Tennessee, have invented certain new and usefulImprovements in Valley-Sheets; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the figures and letters of reference marked thereon.

My invention relates to improvements in metallic roofing, and hasparticular reference to an improved construction of what are termed thevalley-sheets.

In the accompanying drawings, Figure 1 represents a plan view of asection of roofing embodying my invention. Fig. 2 is an enlargedcross-sectional view of a valley-sheet constructed in accordance with myinvention; and Fig. 3 is a perspective view of two adjoiningvalley-sheets, showing the manner in which they are fitted together.

Similar letters of reference in the several figures indicate the sameparts.

Each valleysheet is bent or creased at or about its middle, as at 1, inorder that it may conform to the shape of the roof to which it isapplied. It is also turned back upon itself at each side, so as to formnailing portions 2 of double thickness, through which to drive thesecuring-nails, and both the body of the sheet and the overlappingturned-back portions thereof are formed with one or more coincident ribsor corrugations 3,for the purpose of preventing water from being drivenup onto the nailing portions, as well as for imparting stiffness andstrength to the article along both edges. The turned-back or overlappingportions of the sheet extend considerably beyond the ribs 3, and attheir extremities are turned up slightly in order to facili- PATENTOFFICE.

tate the introduction of the eo-operating roofing-sheets 7, and are alsostiffened and strengthened at said turned-up portions by hems 5, asshown in Fig. 2. Each valleysheet has at one or both of its lowercorners a part of the nailing portion or nailing portions 2 turned backon itself, so as to provide inclines or bevels (3, that facilitate theintroduction of said sheet into the next adjoining sheet, as shown inFig. 3, thus enabling the sheets to be driven together, so as to formtight joints with each other. The exposed surface of the body' of thevalley-sheet is preferably left plain, as shown, though it may be struckup into an ornamental design, if desired. The roofing-sheets '7 whichco-operate with these valley-sheets, may be of any approved kind orconstruction, though I prefer to use such as are covered by my patent,No. 309,459, dated December 16, 1884..

I claim as my invent-ion 1. As an improvement in metallic roofing, theherein-described valley-sheet turned back upon itself at each side andhaving the nailing portions 2, the ribs 3, and the upturned edges 4, asset forth.

2. The valley-sheet herein described, turned back upon itself at eachside and having the nailing portions 2, the ribs 3, and the upturnededges 4, strengthened by the hem 5, as set forth.

3. The valley-sheet herein described, turned back upon itself at eachside and having the nailing portions 2, and the ribs 3, and theturned-over corner 6, for facilitating its introduction into theadjoining sheet, substantially as described.
